Vitual network device (venet) is the default network device for a VE. This network device looks like a peer-to-peer connection between VE and the host system. It does packet switching based on IP header. This is a default network device for VE (an alternative is veth device).

Venet device is created automatically on VE start. Vzctl scripts set up an appropriate IP address and other settings on venet inside a VE.

Virtual network device usage

Adding IP address to a VE

vzctl set <VEID> --ipadd <IP1>[,<IP2>,...] [--save]
Yellowpin.svg Note: This option is incremental, so IP addresses are added to already existing ones.

Example

vzctl set 101 --ipadd 10.0.0.1 --save

After executing this command IP address 10.0.0.1 will be added to VE 101 and IP configuration will be saved to a VE configuration file.

Removing IP address from a VE

vzctl set <VEID> --ipdel <IP1>[,<IP2>,...] [--save]
vzctl set <VEID> --ipdel all [--save]

Example

vzctl set 101 --ipdel 10.0.0.1

After executing this command IP address 10.0.0.1 will be removed from VE 101, but IP configuration will not be changed in VE config file. And after VE reboot IP address 10.0.0.1 will be assigned to this VE again.
